Vigitek LSCB Control Board User Manual

Vigitek LSCB Control Board

Description

LSCB is a control board, developed to simplify the design and use of flashlamp drivers based on power modules by OEM Tech. It provides a possibility for user to set and change an output voltage value for capacitor charger and Pockels cell driver, allows to form the output pulses for discharge circuit(s) and Pockels cell driver with user-defined delays and to vary other parameters. The output signals could be synchronized either internally or externally.
By default, LSCB controls single or dual-channel laser or IPL system with average power from 1 kW to 4 kW level and supports the next devices:

1. One capacitor charger of PCA-series
2. One or two NBU-1012 discharge circuits
3. One Pockels cell driver of QBU- or QBD-series
4. Full set of minor features like IDC, footswitch, synchro input and outputs

Besides, several customized modifications of LSCB are available on request (see also How to order? section):

• “4 channel” version – for high power multi-channel Holmium lasers (it is able to control up to four flashlamps and synchronize their flashes with the rotating mirror)
• “PWM” version – for Nd:YAG, Alexandrite and IPL systems with long and truly rectangular pulses (it works with PWM-based discharge circuits of NBD-series)
• “Pico” version – for picosecond Nd:YAG lasers used in aesthetics (in addition to the standard equipment it is able to control a seed-oscillator driver)
• “RF” version – for aesthetic machines combining flashlamp (laser, IPL) and RF technologies (in addition to the standard equipment it is able to control a RF power module of RFPS-series)
• “Diode” version – for aesthetic machines combining flashlamp (laser, IPL) and diode technologies (in addition to the standard equipment it is able to control a diode driver of PDD-series)
  Base interface to connect LSCB to PC or master control board is RS-232. RS-485 interface, as well as other variations, are available on request. Simple PC software is supplied together with the module.

Please let us know the desired protection level at the moment of order by adding the corresponding suffix to LSCB’s part number:

• -1ms – hardware protection limits maximal pulse width at 1ms level
• -10ms – hardware protection limits maximal pulse width at 10ms level
• -100ms – hardware protection limits maximal pulse width at 100ms level

Appendix 2. RS-232 protocol description

RS-232 connection parameters: 38400 bps, 8 data bit, 1 stop bit, no parity
Command format is: {command} {data (optionally)} {end-of-line}

• Command is 1 to 5 character long (see list below)
• Data is ASCII-string, command and data must be separated with space (space symbol)
• End-of-line symbols are \n or \r\n
• Lowercase commands set values (no return from the controller), uppercase commands return values. For example, if “v 300” sets voltage to be 300, ”V” returns 300. So, set and get command of the certain value have the same letter, but set command is lowercase, and get is uppercase.
• Monitor commands (uppercase, but with preceding ‘m’ letter) only return values.
• Every command (except monitors, that begin with letter m) has limits (lower and upper) that can be established by _cmd and ^cmd commands, where cmd is certain command. For example, _p and ^p establish lower and upper bounds of available pulse length. Note: you may narrow allowed range of the command with respect to default range, but widening may lead to abnormal functioning. We strongly recommend to contact the manufacturer before extending the operating limits. Maximum range of _cmd and ^cmd commands: -214748364.8 … 214748364.6 for commands f, !k0, !s, !r and -2147483648 … 2147483646 for other commands. _CMD and ^CMD return lower and upper bounds of command cmd.

• -z – resets QBU voltage calibration
• @ – ‘poll all’ command – returns values of all parameters in certain order – order can be read by use of ‘=’ command
• = – returns order in which ‘poll all’ command returns values
•  % – ‘poll limits’ command – returns all limits of all parameters which have limits – limits are returned in order “min max step”
•  There is a possibility to create user-defined poll list using @a, @b, @c, @d and @e commands – @a V HV F P – creates a user-defined poll list of V HV F P parameters – @A – returns list of V HV F P parameters (e.g. 247 2000 9.5 273) – =A – returns list order (V HV F P) – %A – returns all limits of all parameters in list in “min max step” order (e.g. 100 700 1 2000 5000 1 0 50.0 0.1 50 100000 1)
• .v – resets all values stored to EEPROM to default
• !fb – forbids EEPROM from writing
• .u – runs the bootloaders – a complete set of bootloader commands is available on request

Appendix 3. Parameter presets

All parameters are adjustable and can be re-set by the customer via software or RS-232 commands
